I've recently read about a scandal with Vickers and a Dutch order for some revolvers, which happened about 1919. The author claims that Vickers "unexplicably" outsourced the order, and the quality of the revolvers supplied was so awful, that many wouldn't even fire. Admittedly, this story has little to do with shotgun making, but it makes me wonder whether the gun in question was made in-house or oursourced?
